Have you been able to find the example in the documentation?
http://docs.racket-lang.org/reference/pairs.
A good example, it is like map, but for when you only care about side
effects.

I don't know if it's a particularly good example, but here's a basic usage
of for-each:
#lang racket
(define lst '(apple banana cherry))
(for-each
(lambda (x)
; x is bound to each item of lst in turn
(printf "item:~a~n" x)
; do something more with x
)
lst)
Hope this helps,
